20 claims

Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 1

Original Legal Text

1. A method in an electronic device, the method comprising: connecting a Universal Serial Bus (USB) device to the electronic device at a first connection speed the USB device among a plurality of connection speeds; displaying a menu to receive an user input for enhancing the first connection speed on a display of the electronic device; in response to receiving the user input for enhancing the first connection speed, determining whether a faster connection speed of the USB device is available among the plurality of connection speeds than the first connection speed; and reconnecting the USB device to the electronic device at the faster connection speed of the USB device when the faster connection speed of the USB device is available.

Plain English Translation

An electronic device connects to a USB device at a specific speed (e.g., USB 2.0). The device displays a menu option allowing the user to request a faster USB connection. If the user selects this option, the device checks if a faster speed is supported by both the host and the USB device (e.g., USB 3.0). If a faster speed is available, the device disconnects and reconnects the USB device, establishing the connection at the faster speed.

Claim 2

Original Legal Text

2. The method of claim 1 , further comprising displaying the first connection speed on a display unit of the electronic device.

Plain English Translation

In addition to the process of connecting at a faster USB speed, the electronic device displays the current USB connection speed on its screen, so the user knows the current connection speed before requesting an enhancement.

Claim 3

Original Legal Text

3. The method of claim 1 , wherein recognizing whether an enhancement event is generated comprises recognizing whether there is an attempt to connect at a connection speed that is faster than the first connection speed.

Plain English Translation

The enhancement event, which triggers the attempt to use a faster USB speed, is recognized when the electronic device detects that the USB device is attempting to connect at a higher speed than the currently established speed.

Claim 4

Original Legal Text

4. The method of claim 1 , wherein enhancing the first connection speed of the USB device comprises blocking power which is being supplied to the USB device and supplying power again.

Plain English Translation

To enhance the USB connection speed, the electronic device temporarily cuts off the power supply to the USB device and then restores the power. This disconnection and re-initialization can force the USB connection to renegotiate at a potentially faster speed.

Claim 5

Original Legal Text

5. The method of claim 1 , wherein enhancing the first connection speed of the USB device comprises changing a level of current which is being supplied to the USB device.

Plain English Translation

To enhance the USB connection speed, the electronic device changes the amount of electrical current being supplied to the USB device. This adjustment in current levels can sometimes influence the USB device to operate at a higher connection speed.

Claim 6

Original Legal Text

6. The method of claim 1 , wherein enhancing first the connection speed of the USB device comprises changing a USB phytune register value.

Plain English Translation

To enhance the USB connection speed, the electronic device modifies the value of a USB PHYtune register. These registers control the physical layer settings of the USB interface and can be adjusted to optimize performance and achieve faster connection speeds.

Original Legal Text

8. The method of claim 1 , further comprising changing a value of a register and wherein an equalizer is a chipset for reinforcing a high frequency component attenuated by transmission lines.

Plain English Translation

The electronic device enhances connection speed by changing the value of a register and uses an equalizer circuit, a component that strengthens high-frequency signals weakened during transmission along wires or circuit boards, which can help to improve data transmission and allow for faster connection speeds.

Claim 9

Original Legal Text

9. The method of claim 1 , further comprising displaying a connection speed restoration menu of the USB device when the first connection speed is determined.
